TIG solid rod for nickel alloy
NiCrFe type/For Inconel 690 alloy
Применение:
1. Suitable for the welding of Ni-Cr-Fe type, especially suitable for nuclear power plant projects such as welding for Inconel 690 alloy; 2. Can also be used for cladding of corrosion resistance acid corrosion layer and dissimilar meta welding between Inconel and Incoloy alloys.
Характеристики:
1. Ni-Cr-Fe type argon gas shielding TIG rod, with nominal composition 60%Ni-29%Cr-9%Fe; 2. The high Cr content provides excellent stress corrosion cracking resistance in radioactive pure water environment; 3. Stable arc, beautiful weld bead appearance, great iron water fluidity, and excellent weldability.

Замечания по использованию:
1. Shielding gas: Pure Ar; 2. Interpass temperature: <=100℃, and reduce the heat input as much as possible. The above recommendation is for your reference, actual operation depends on the conditions on site; when necessary, prepare WPS first before deciding the corresponding welding methods.
